And finally, there's what HP describes as its "first fully interactive, 42in diagonal, high-definition digital signage touch display," the HP LD4200tm.
Designed for use in kiosks, retail premises, travel terminals, hotel lobbies, and similar locations, the multitouch screen provides full HD resolution (1920 x 1080) with a 178 by 178 degree viewing angle.
The LD4200tm is designed for round-the-clock operation with low power usage and good longevity, HP officials claimed.
Prices start at $US2799.
Most of the products announced will ship on October 22, though the TouchSmart 300 is due on November 1, with the TouchSmart 9100 and LD4200tm following in December.
